Help with FME7-to-MMC5 conversion of Hebereke

Help with FME7-to-MMC5 conversion of Hebereke
by on (#77483)
I am trying to convert a rom of Ufouria/Hebereke to MMC5, distributable via IPS or other Patch,

I removed the IRQs succesfully, then I replaced Mapper's PRG and CHR bank for MMC5 regs, But MMC5 does not work,

If you want to figure out how to do the mapper 5 fixes, Contact me via E-Mail and I will give the rom

Email is either Hamtaro126@ymail.com, or JAJJMM@MSN.COM

Or just make a patch with Xdelta?

Does the MMC5 allow for PRG-ROM in $6000-$7FFF like the FME-7 does? I dunno, it's just one incompatibility possibility.

According to the wiki, no. Bit 7 of $5113 does not appear to exist. How many different pages are loaded into $6000-$7FFF over the course of a game? If the bank is not switched rapidly, consider copying segments into PRG RAM.

All I know is that in both Ufouria and Hebereke: 6000-7FFF is unused,

But I implented it, the problem is the debugging, some of it seem to not like my changes, therefore rejecting the PRGROM regs that I made changes,

I removed all instances of $8000 and extra temp reg $22 which in turn goes with $8000, replacing all of the regs in thier proper places, but does not work when testing

Notes that I have with banks:

$41 = $5114 ($8000-9FFF)
$40 = $5115 ($A000-BFFF)
DPCM/Misc bank switchable at C000-DFFF
Fixed bank at $E000-FFF5
Vectors at $FFF6-FFFF
